Examples with SpecProducer org.apache.gobblin.runtime.api.SpecProducer used on opensource projects

Example 1 with SpecProducer

use of org.apache.gobblin.runtime.api.SpecProducer in project incubator-gobblin by apache.

the class Orchestrator method orchestrate.

public void orchestrate(Spec spec) throws Exception {
    // Add below waiting because TopologyCatalog and FlowCatalog service can be launched at the same time
    this.topologyCatalog.get().getInitComplete().await();
    long startTime = System.nanoTime();
    if (spec instanceof FlowSpec) {
        Map<Spec, SpecExecutor> specExecutorInstanceMap = specCompiler.compileFlow(spec);

            return;
        }
        // Schedule all compiled JobSpecs on their respective Executor
        for (Map.Entry<Spec, SpecExecutor> specsToExecute : specExecutorInstanceMap.entrySet()) {
            // Run this spec on selected executor
            SpecProducer producer = null;
            try {

Example 2 with SpecProducer

use of org.apache.gobblin.runtime.api.SpecProducer in project incubator-gobblin by apache.

the class Orchestrator method remove.

public void remove(Spec spec) {
    // Note: Current logic assumes compilation is consistent between all executions
    if (spec instanceof FlowSpec) {
        Map<Spec, SpecExecutor> specExecutorInstanceMap = specCompiler.compileFlow(spec);
        if (specExecutorInstanceMap.isEmpty()) {

            return;
        }
        // Delete all compiled JobSpecs on their respective Executor
        for (Map.Entry<Spec, SpecExecutor> specsToDelete : specExecutorInstanceMap.entrySet()) {
            // Delete this spec on selected executor
            SpecProducer producer = null;
            try {
                producer = specsToDelete.getValue().getProducer().get();
                Spec jobSpec = specsToDelete.getKey();
                _log.info(String.format("Going to delete JobSpec: %s on Executor: %s", jobSpec, producer));
                producer.deleteSpec(jobSpec.getUri());
            } catch (Exception e) {
                _log.error("Cannot successfully delete spec: " + specsToDelete.getKey() + " on executor: " + producer + " for flow: " + spec, e);
            }
        }
    } else {
        throw new RuntimeException("Spec not of type FlowSpec, cannot delete: " + spec);
